Photos: Solar festival as green as it gets

This is the second year that David Katz wheeled his solar-powered automated teller machine to SolFest. Each user paid $5 per transaction to withdraw cash, a dollar of which went to the Solar Living Institute. Katz founded AAE Solar, which has been selling photovoltaic equipment to homeowners and businesses since 1979.
